Improvement in churns



LEVI DEDERIOK, OF NEW YORK, NQ Y.

Letters'Patent No. 107,464, dated September 20, 1870.

IMPROVEMENT IN. CHU'RNS.v

The Schedule referred to in these Letters Patentfand making part of the same suitable box, A, may be made, witlra crank-shaft, B,

passing through the box..

Upon this shaft are hung two revolving boxes or beaters C C', lig. 2.

As these boxes revolve in the direction indicated by arrows, the' cream is carried np into the air and poured out, to run down over the corrugated surfaces 1), thus eifectually mixing with the air, while it is also thoroughly agitated. As the 'boxes descend `they carry air down int-o the cream.

By making the boxes in two or more divisions on each side of shaft, as shown at G and C, the air is carried, in part, very near the bottom ofthe churn or box, and, also, part of the cream is carried near to the top ofthe churn, where it is poured out, mixing with 'the air as it falls or flows down. v

The corrugated surface D is very eliicient in agitating the cream, and in mixing the same with the air.

I have so arranged -the respective parts as to give just enough agitation, and, also, the requisite amount of air, for eiicient churning.

lhe top ofthe box is covered by a set of revolving slats, E, similar to a Venetian window-blind.

By this construction, more or less air may be admitted, as desired, and yet prevent the cream from spattering or splashing over the top otthe box. ltr-is, also, easy to examine the cream, and notice when the churning is completed.

Ipropose to revolve the beaters or boxes very slowly, yet I tind that the butteris produced and collected into balls in a very short time.

Having described my invention,

I claimv l 1. VThe use' of the revolving beater, constructed with boxes C C', and alternate corrugated surfaces D, or

their equivalent, substantially in the manner aud fory the purpose set forth.

2. In combination with the above and the box, the cover, consisting of revolving slats, substantially as set forth. LEVI. DEDERIGK.
